TAUNTON — A four-year environmental bond bill, including $10.2 million in funding for park improvement projects in Taunton, was approved on Thursday by a StateHouse conference committee.

Additionally, the bill also includes $5 million toward the creation of an Eastern Regional Center for Urban Sustainability at Bristol County Agricultural High School in Dighton, said state Sen. Marc Pacheco, D-Taunton, who was on the bond conference committee along with five other legislators. There is also $100,000 set aside for the development and installation of a solar energy farm at the school.

The Senate originally passed the $1.9 billion bond bill in early July, adding $200 million to the House version of the bill. The environmental bond bill will authorize Gov. Deval Patrick and the next elected governor to release the funding.

In Taunton, the project would make millions available to improve the Boyden Wildlife Refuge, in addition to other public parks in the city.

The bill includes $5 million for improvements to the refuge and an adjacent piece of conservation land in Taunton, in accordance with the 2002 Boyden Park/Conservation Land master plan, Pacheco said.

Other projects in Taunton include $2 million for the construction of a trail around Watson Pond and for connecting access trails in Watson Pond State Park, which Pacheco said would help attract corporations to the Myles Standish Industrial Park located next to the park. Also, $400,000 is provided in the bill to reconstruct the Sabbatia Lake boat ramp and to rebuild the boat ramp parking. In addition, $790,000 is provided to repair Big Bearhole Dam in the city.

The bond bill also provides a total of $2 million to Taunton for improvements to Hopewell Park, Memorial Park, Weir Field and Whittenton Field, although it’s not clear how exactly the funding will be used.

Outside of Taunton, the environmental bond bill provides $500,000 for land to protect a drinking water well field in Dighton, and $5 million to create a University of Massachusetts Cranberry Research Station in East Wareham.

Statewide, some of the biggest projects in the environmental bond bill include a $100 million effort to design, construct and preserve parks, forests and other recreational sites. Another $100 million project in the bill would dredge Boston and New Bedford harbors. The bill also includes provisions to control the overpopulation of deer.
